Earlier quoted context omitted.
Nothing is perfect, but also remember that people always find things to complain about, particularly if they don't have personal experience of less well functioning systems.
By that logic, no one should complain about anything, because we don't live in literal hell. But that is of course preposterous.
Person A from place without infrastructure X: wow, life with infrastructure X sure would be better. I wonder if we should invest in X?
Person B from place with infrastructure X: There's lots of problems and it annoys me daily.
Note that in this situation, the wrong conclusion is to say "well, then maybe infrastructure X is a bad idea". We want to avoid that line of thinking (since it's not an appropriate conclusion given the statements), so it's worth pointing out many tempering factors, such as those mentioned by the parent comment.
